The Diffie–Hellman key exchange lets two parties agree on a shared secret over an open channel, a breakthrough that made modern secure internet communication possible. It was published in 1976 by Whitfield Diffie and Martin Hellman, who was born into a Jewish family in New York. Hellman later shared the 2015 Turing Award, computing's highest honor, for this pioneering work in public-key cryptography.
